LOADING OPTIMIZATION OF THE METAL TRUSSES

open access: yesBulletin of Belgorod State Technological University named after. V. G. Shukhov, 2020
Loading optimization of the metal trusses has a variational basis. The universal criterion of optimization is the minimum of potential energy of the system (additional energy) in functional space expanded at the expense of functions fields of configuration and (or) material modules, and load.

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures

open access: yesStructural Concrete, EarlyView.
Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

The influence of secondary reinforcement on a strut‐and‐tie model for the design of reinforced concrete corbels

open access: yesStructural Concrete, EarlyView.
Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

A compliance based design problem of structures under multiple load cases

open access: yes, 2010
There are two popular methods concerning the optimal design of structures. The first is the minimization of the volume of the structure under stress constraints. The second is the minimization of the compliance for a given volume. For multiple load cases

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Fracture‐mechanical numerical simulation of punching in reinforced concrete foundations considering soil‐structure interaction and design code evaluation

open access: yesStructural Concrete, EarlyView.
Abstract Current design provisions for punching shear in foundations, including Eurocode 2 (2023) and fib Model Code 2020, are mechanically based models partly calibrated against experimental data from isolated flat slabs and foundation specimens. The available experimental database for foundations is small and only partly representative of realistic ...

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

The reliability of the support zone of beams formed with the use of ST models

open access: yesBudownictwo i Architektura, 2013
The following paper presents the analysis of the reliability assessment of a reinforced concrete beam whose shear zone was formed with the use of various truss models. Model 1 is a truss model that was generated using topological optimization. Model 2 is

A New Model of Feeding Biomechanics Based on Tied‐Arch Principles

open access: yesIntegrative Zoology, EarlyView.
This new biomechanical model explains the major stress and strain patterns generated through the cranium during biting. The model proposes that the cranium resolves bite‐induced reaction forces through arcs of compressive stress that span the cranial structure between biting teeth and both jaw joints.
